I received an email from a gentleman who is a motor home owner and tows a car trailer that wanted a bit of help. Here’s what I received:
Dear Caravan Chronicles I hope you can help. I have a motorhome which I use to pull a car trailer to classic car racing events. My trailer currently has a Warn winch to help load and unload my sports car but I have recently had a caravan motor mover fitted to help with manoeuvring the trailer with the car loaded. The trailer has one 110Ah battery fitted for the winch, which I have to charge by plugging in the trailer to a mains socket in the motorhome. I asked the company installing the mover if they could install a second 110 Ah battery for the mover and make it so I could charge both batteries while towing. Unfortunately they said it could not be done. I also asked if they could make it so I could link the two batteries if required with a switch, which they also said couldn’t be done. They did advise me to talk to the people that fitted the tow bar. To cut a long story short they also said what I wanted could not be done. Can you come up with something that would work? Many thanks XXXXXXXXAfter a couple of email exchanges to confirm a few things, here’s what I came up with:
